Application: Construction
In the booming construction industry, from tunnel excavation, concrete spraying to pneumatic support of aerial equipment, stable and reliable compressed air is the key to ensure the progress and quality of the construction. ZAKF, a brand of Dongguan Jubilee Compressor Fittings Co., Ltd, has launched a 30hp fixed-speed
Screw Compressor, which has become an ideal air source solution for many construction projects due to its high efficiency, low noise, stability and durability, and intelligent control.
A large-scale subway tunnel construction project undertaken by a Chinese construction company was faced with a complex and changing construction environment and stringent schedule requirements. The air compressor used before was difficult to adapt to the humid and dusty environment in the tunnel, and frequently broke down, resulting in unstable air pressure in the concrete spraying equipment, many delays in the construction progress, and economic losses of up to 200,000 yuan per month due to equipment problems. The project manager, Mr. Zhao, said, “The environment at the construction site is harsh, and it is difficult for ordinary air compressors to run stably for a long time, which not only affects the efficiency, but also significantly increases the maintenance cost.”
With the introduction of the ZAKF
30 HP Screw Air Compressor, the construction problems were solved. The ZAKF 30hp fixed-speed screw compressor adopts a third-generation toothed-screw mainframe with low-speed operation (about 1500 - 3000rpm) and direct-drive structure, which achieves a low noise level of 74±2dB (A) at a pressure of 0.7 - 1.2MPa to minimize the disturbance to the construction site personnel. Meanwhile, the 100% transmission efficiency and reduced wearing parts design significantly reduce the maintenance frequency. The intelligent control system ensures stable air supply even in the tunnel's high humidity and fluctuating temperature (-5°C to 50°C) by adjusting the air inlet valve in real time. Manager Zhao is pleased to share, “After the 22 kw screw air compressor was put into use, the stability of the concrete spraying operation was significantly improved, the construction efficiency was increased by 30%, the equipment failure rate dropped by 70%, the monthly maintenance cost was saved by more than 80,000 yuan, and the project schedule was also successfully advanced.”
In addition to its outstanding performance, the ZAKF 30 HP Screw Air Compressor has also won the trust of construction companies thanks to the high reliability of its Class F insulated motor and its long service life of over 50,000 hours. Its cooling system adapted to extreme environments ensures that the equipment can operate stably in cold or hot construction sites. In addition, Dongguan JOBE Compressor Fittings Co., Ltd. provides a full range of after-sales services, including a one-year warranty, a sufficient stock of original spare parts, and a team of professional engineers for installation, commissioning and regular maintenance services, to ensure a continuous and stable supply of gas for construction projects.
